CUATBNG PREPARATION.

SPECIFICATION forming part of Letters Patent No. 690,915, dated January 14, 1902. Application iiled September 20, 1901I Serial No. 75.930. (No specimens.)

T0 ctZZ whom t may concern.-

Be it known that I, HARRIETA. BENTLEY, a citizen of the United States, residing at Glens Falls, in the county of Warren and State of New York, have invented a new and useful Coating Preparation, of which the following is a specification.

This invention relates to an improved material for artists use and a coating comppund for preparing surfaces other than a canvas surface to receive oil-paints or water-colors and to serve as a protection for engravings, prints, or the like, and the purpose of the preparation is to provide a cheap substitute for canvas and other expensive material and preserve the necessary qualifications of the latter for painting purposes, as well as to prepare the surfaces of engravings and prints so that lthey may be exposed without a covering-glass and be protected from injury.

In the accompanying drawing, forming a part of this specification, and in which like letters of reference indicate corresponding parts, there is illustrated diagrammatically one form of procedure for carrying the invention into effect, it being understood that the invention may be otherwise carried out without departing from the spirit of the invention, and in the drawing,r the iigure is a view in sectional elevation, exhibiting a backing having applied thereto the surfaces constitu ting the present invention.

ln carrying the invention into effect a suitable backing A, which may be of pasteboard, wood, paper, or textile fabric, is taken and has applied thereto a double coating of substances adapted for receiving oil or water colors. The first coating B consists of p yroxylin, a suitable menstrua therefor, prefera-bly`- amyl acetate, and a non-rapid-dryin g oil, preferably oil of cedar, in the proportions of about one drain of the pyroxylin to a half a pint of the amyl acetate and of the oil a quantity equal to about a large teaspoonful, the oil being added to cause the mixture to spread smoothly and to prevent too-rapid drying. The second coating C consists of a gelatinous substance, such as isinglass, reiined glue, gelatin, or the like; but on account of its cheapness and the readiness with which it may be applied isinglass will generally be preferred, and a sufficient quantity of this is taken and boiled in Water to present a stiff jelly when cold.

In the use of this preparation any quality of papersuch as paste'ooard, either white or coloredhas the first-mentioned compound applied thereto by means of a soft brush or any other article that will evenly spread the same. In some cases the pyroxylin may be omitted and the surface coated with the mixture of amyl acetate and cedar-oil. After' the paper is so prepared the surface is further coated once or twice with the isin glass or other jelly by means of a fine stiff brush, and after drying the paper so treated will be ready to receive oil-colors or water-colors, as may be desired. Then the surface of the paper is prepared as set forth, any primary glaze or gloss will disappear, and the paper instead of being used for receiving paints may be employed for constructing various articles and capable of being cleansed Without causing a warpage of the article. The paper alone will also be prevented from warping or blistering when used for painting purposes after preparation in the manner set forth, and woods may also be prepared in a similar manner and be made capable of receiving a suitable surfacecleansing material, such as Water, Without affectin g the finish or causing the same to warp. Vhen wood is prepared in this manner, it will have a lusterless finish adapted to receive paints without liability of running, a condition much soughtafter by artists. Textile fabrics other than canvas-such as silks, linen, and the like-are treated with a coating of the first-mentioned compound,and thereby adapted to receive oil-colors, thus making the work of tapestry-painters very much easier. The treatment of the several materials set forth with the compounds does not materially change the appearance of the same, and it is also intended to prepare thin papers in the same manner as pasteboard.

Photographs, engravings, or other pictures in black and White when treated with the cornpound makes the work of the reproducer comparatively easy, for when the said engravings or pictures are painted with oilcolors they closely resemble a genuine oilpainting, equally clear and beautiful in tint and more beautiful in tint than pictures IOO painted over photographs on canvas, because more minute Work can be done on paper than on canvas. Coarse Work may also be pursued, according to the quality of the paper. The colors should be thinned with spirits of turpentine or oil and spirits of turpentine or naphtha. The colors should be applied sparingly, so that the shadows and outlines will show through the paint, and transparent oilcolors should be used as much as possible. When not painting over photographs or engravings, the paint may be applied exactly as on canvas, using a little turpentine-spirits or other drier. Body water-color may also be used on rough paper when prepared by the application of the compounds. In treating engravings and other pictures with the compounds a light quick touch is essential, so as to avoid injuring or destroying the picture.

Many other substances than those mentioned may be prepared with the compounds, and a material economy in the use of painting foundations or surfaces will result.

Having thus described the invention, what is claimed as new isf 1. A sheet of material for artists use, said sheet having` a painting-surface coated with a mixture of amyl acetate and cedar-oil.

2. A sheet of material for artists use, said sheet having a painting-surface coated With a mixture of amyl acetate, cedar-oil and pyroX'ylin.

8. A sheet of material for artists use, said sheet having a painting-surface coated With a mixture of amyl acetate, cedar-oil and pyroXylin in or about the proportions specified, and an outer coating of a gelatinous material.

4. The herein-described compound for preparing surfaces consisting of amyl acetate and cedar-oil.

5. The herein-described compound for preparing surfaces consisting of pyroXylin, amyl acetate, in or about the proportions set forth, and a gelatinous material.

6. The herein-described compound for preparing surfaces consisting of pyroxylin, amyl acetate, in or about the proportions set forth, and isinglass in the form of jelly.

In testimony that I claim the foregoing as my own I have hereto afxed my signature iu the presence of two Witnesses.
